I guess in this example ViolationColumnNames should be turned into a list before passing it to the drop method:

>>> violationColumnNames = filter(lambda columnName: 'Violation' in columnName, nyc_data_raw.columns)
>>> with ProgressBar():
>>>     nyc_data_raw.drop(violationColumnNames, axis=1).head() 

should be:
ViolationColumnNames = list(filter(lambda columnName: 'Violation' in columnName, nyc_data_raw.columns))
